High Quality: In PLA-based material; Environmental protection; Good toughness; Good liquidity; Good flexibility PLA PLA (Polylactic Acid) thermoplastic filament is a premium grade material derived from renewable resources such as corn. It has low odor and is guaranteed to be free from heavy metals, phthalates or BPA. PLA has much less tendency to warp compared to ABS, although it can still warp a little in a cold environment or on large objects. Although PLA can be printed both with and without a heated print bed, if your desktop 3D printer does have a heated print bed it is recommended to set your print bed temperature to approximately 40° to 50°C which will relax the lower layers of your print without overheating them. One easy way to deal with this, is to have an active cooling fan cooling down the PLA immediately after it exits the nozzle. PLA is derived from corn starch and is biodegradable in an active compost heap. Print temperature range: 190 – 220 ℃ , the ideal is 210℃ and this value will little variable due to different color and printer temperature sensor. Diameter: 1.75mm ± 0.02mm Heated Bed: Not required but can be used (up to 60 °C) Recommended Printing Speed: 30 – 60 mm/s
